USP Glycerin IR Absorption

This USP test method determines glycerin concentration utilizing Fourier Transform Infrared Spectroscopy (FT-IR).

USP Acidity or Alkalinity in Ethanol

This USP test method measures the acidic or alkaline impurities present in ethanol. The procedure involves titrating a specified volume of ethanol with a standard acid or base solution to determine its acid or alkali content.

USP Glycerin Limit of Glycol

This USP test method follows the glycol determintation procedure directly from the USP Monograph for glycerin.

Total Starch [Resistant WITHOUT Sugars]

This test method is an enzymatic-colorimetric method used to determine total starch content in foods and feed, less the sugars washed away in an ethanol pre-treatment. The method involves enzymatic hydrolysis of starch into glucose, followed by quantification using a glucose oxidase-peroxidase (GOPOD) assay.

Total Solids [Manure]

This test method is a calculation method utilizing the moisture of manure samples to determine the amount of solids found within the manure.

Total Solids

This test method is a gravimetric procedure for determining Total Solids (TS) in water, wastewater, and sludge samples by measuring the residue remaining after drying.

Total Plate Count [Petrifilm – Anaerobic]

This test method is an approved method for determining the anaerobic plate count or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of 48 hours in an anaerobic environment.

Total Salts [Manure]

This test method is a calculation method utilizing the conductivity of manure samples to determine the concentration of salts found within manure.

Total Plate Count [Petrifilm – Rapid]

This test method is an approved method for determining the aerobic plate count (APC) or total viable count in food and dairy products. It is widely used in food safety, quality assurance, and environmental monitoring as a rapid, space-saving alternative to traditional agar methods, with an incubation period of only 24 hours.

Total Starch [Resistant w/ Sugars]

This test method is an enzymatic-colorimetric method used to determine total starch content in foods and feed. The method involves enzymatic hydrolysis of starch into glucose, followed by quantification using a glucose oxidase-peroxidase (GOPOD) assay.
